摘要：In this paper, monolithic TS-1 (a zeolitic material containing both silicon and titanium) was successfully synthesized on polymer-modified carbon nanotubes/nickel foam (PMTS-1). PMTS-1 had high surface areas and aggregated pores (confined pores formed in an aggregated structure), and TS-1 could be evenly dispersed on the surface, which could facilitate reactant transport and improve dispersibility of TS-1. TS-1 strongly interacted with the polymer-modified CNTs/NF and is highly dispersed because the PDDA-modification could enhance the positivity of CNTs/NF. PMTS-1 was beneficial to the adsorption of the reactant propylene and the desorption of the product propylene oxide, which reduced the side reaction of the deep oxidation of propylene oxide, pore blocking, and coke formation. Also, the adsorption capacity of PMTS-1 to H2O2 was enhanced, which created a microenvironment conducive to the forward reaction. After the reaction, PMTS-1 was easily separated from the reactants, which offered an economical application prospect. Copyright ? 2019 American Chemical Society.
